Daylight appears to be one of the most important visual and sensual elements of hospital environment for patients ’ health
and wellbeing and is often given insufficient priority by researchers, due to its versatility and far-reaching but complex
implications. The information related to daylight in hospitals is spread over a wide range of articles and research reports
done by either biologists or researchers of therapeutic built environment. Therefore, it is difficult for daylight researcher to
link these two and get a complete picture of the possible influences of therapeutic daylight. This paper is aimed at
compiling and arranging the findings of two research groups in a line to explore how daylight impacts on patients ’ health
and recovery gradually from light incident on patients ’ eye or skin, to the evidences of patients ’ health outcomes in
hospital environment. The findings from literature review will strengthen the foundation of researchers who want to
investigate the effect of daylight on clinical recovery and intend to design therapeutic daylit hospital buildings.
